AUTO PULL-OUT.

Specification of Letters Patent.

Patented Feb., i9, i918.

Application filed. October' 3, 1917. Serial No. 194,564.

To @ZZ 'Lv/tom t may concern.'

Beit known that l, Louis Hannan, residing at Olds, in the Province of Alberta, Dominion of Canada. have invented a new and Improved tuto Pull-Out, of which the following is a specification.

My invention has for its object to provide a simple and inexpensive attachment for motor vehicles that can be conveniently applied to any of the ordinary types of motor vehicle frames and which may be quickly adjusted for utilizing the motor powei for pulling the vehicle out of ruts, mud holes, etc.

Another object of my invention is to provide an attachment for the purpose stated adapted for being compactly mounted on the vehicle chassis, at the front end thereof, and having a driving member arranged for being quickly coupled with the engine 'shaft when the attachment is to be used for pulling the vehicle out and which is as readily disconnected from the engine shaft after having exerted its function.

llVith other objects in view, that will hereinafter appear, my invention resides in an attachment of tl e character stated, that embodies the peculiar construction and novel arrangement of parte. all of which will be hereinafter fully described, specifically pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Figure l is a perspective view of my invention, the same being shown iu the operative position on motor vehicle.

Fig. 2 is a front view of the attachment.

Fig. 3 is a plan view thereof as applied to the vehicle framing.

Fig. Ll is a perspective view of the winding drum, and the worm or power transmitting shaft, separated.

Fig. 5 is a detail cross section of my pullout device on the line of Fig. 2.

6 is a similar view taken on the line 6 6 on1 Fig. 2.

ln the practical arrangement, my pullout attachment comprises essentially a pair of end brackets 1 1 shaped for being suitably bolted to the steel bars or frame members 2, as is best shown in Figs. 2 and 3, by reference to which it will be noticed a power shaft 4 journals at its ends in the said brackets 1 1.

One or more, two being shown, cable winding drums 5 5 are keyed onto the shaft 4 and midway, between the two drums, a worm wheel 6 is mounted to turn with the said shaft.

Coperative with the worm wheel Gis a worm screw that forms a fixed part of power transmitting shaft 7 that ournals in bearing boxes SO S0 on a two-part boxing 8, secured by bolts 9 9, to the top or cross members 2 2 of the front frame members, as shown.

Shaft 7 has a clutch end 7l and the said shaft is endwise slidable, with respect to its journal bearings and the worm screw, lo

adapt it for being readily shifted into a clutched engagement with the engine shaft, see on Fig. 8, when it is desired to transmit the engine power to the cable drum.

F rom the foregoing description taken in connection with the drawings, the general arrangement and the manner of the use of my invention will be readily apparent.

The arrangement of the several parts that constitute my attachmentis such that they may be readily applied to any of the usual types of motor vehicles with practically no changes or alterations in the parts of the framing to which the attachment is to be applied.

In practice, one or both of the drums may carry cables 9, having one end attached to the drum and the other end equipped with a claw hook l() to provide for hooking onto a tree or stake, as indicated in Fig l of the drawings, from which it is apparent that should the vehicle `get stuck from any of the usual causes, it is only necessary to hook the free end of the cable or cables around the stakes or trees, above the screw shaft into a clutched engagement with the engine shaft and start the engine and thereby pull out the vehicle under its own power After the auto is pulled out, the pullout is rendered inoperative by shifting the shaft 7 out of engagement with the engine shaft.

l. In an automobile having a chassis frame and an engine provided with a crank shaft; a skeleton truss frame. secured transversely to the chassis frame in front of the machine and having .spaced front and back truss members, bearing brackets carried by said truss frame and located between the front and back truss members, a drum car-V rying shaft journaled in said bearing brackets transversely of the machine, said truss frame having a top bearing structure, a Worm shaft journaled in bearings in said top bearing structure, a Worm gear on said drum shaft meshing with the Worm of said Worm shaft, and means to couple said Worm shaft to the engine shaft at will.

2. In an automobile having a chassis -frame and an engine provided with a crank shaft; a skeleton truss frame secured transversely to the chassis frame in front of the machine and having .spaced front and back truss members, bearing brackets carried by said truss frame and located between the front and back truss members, a drum carrying shaft journaled in said bearing brac :ets transversely of the machine, said truss frame having a top bearing structure, a Worm shaft journaled in bearings in said top bearing structure, a Worm gear on said drum shaft meshing with the Worm of said i Worm shaft, and means to couple said Worm shaft to the engine at Will, said bearing structure comprising a body, a central opening and front and back bearing surfaces and a bearing cap also having front and bacl bearing surfaces, said Worm shaft having` bearing portions journaled in saidrbearing ,surfaces with the Worm located in the open portion between the front and back bearing surfaces substantially as shown and described.

LOUIS HAMMER.
